Documented Uses

• CIR ingredient: Disodium Etidronate
• For the treatment of symptomatic Paget's disease of bone and in the prevention and treatment of heterotopic ossification following total hip replacement or due to spinal cord injury.
• Information on 1 consumer products that contain Disodium Etidronate in the following categories is provided:
• Phosphonic acid, P,P'-(1-hydroxyethylidene)bis-, sodium salt (1:2): ACTIVE
• Agents that inhibit BONE RESORPTION and/or favor BONE MINERALIZATION and BONE REGENERATION. They are used to heal BONE FRACTURES and to treat METABOLIC BONE DISEASES such as OSTEOPOROSIS.
• Not metabolized. Route of Elimination: Etidronate disodium is not metabolized. Within 24 hours, approximately half the absorbed dose is excreted in urine; the remainder is distributed to bone compartments from which it is slowly eliminated. Unabsorbed drug is excreted intact in the feces. Half Life: In normal subjects, plasma half-life of etidronic acid, based on non-compartmental pharmacokinetics is 1 to 6 hours.
